BACKGROUND

1. Technical Field

This disclosure relates generally to power management, and, more specifically, to managing power consumption in display systems.

2. Description of the Related Art

The revolution in mobile computing devices, also described herein as multifunction devices, has progressed at a far greater pace than the progress of the batteries that power mobile devices. From smart phones to tablets to laptops, users face increasing frustration as batteries drain under the ceaseless consumption produced by modern display devices.

As the multifunction devices improve and provide an increasingly sophisticated array of functions to the user, demand for power increases on two fronts. First, the amount of time that devices are in use increases. Second, improved hardware such as brighter display screens and faster processors drains more battery power for each minute that the multifunction device remains in use.

Most, if not all multifunction devices (e.g., smart phones) have a constant screen size and a display area with two options only; this is, the devices are either in a full display state (e.g., the entire display screen is powered on) or in a no display state where the entire display screen is powered-off.

SUMMARY OF EMBODIMENTS

Systems and methods for managing display power consumption are disclosed. In some embodiments, screen space configuration and user or automated management of the display may cause portions of the display as well as elements displayed by the display to be configured to any user-selected size or position. The battery-saving benefit resulting from this new empowerment may be an extremely valuable function, in some embodiments.

In some embodiments first information is displayed in an available display area including a first portion of a display screen in a configuration having a set of portions. The set of portions includes the first portion of the display screen, which is configured in a powered-on state to perform display functions and receive user input, and a second portion of the display screen, which is configured in a powered-off state. Responsive to a user indication in the first portion, the second portion is added to the available display area by transitioning the second portion to the powered-on state to perform display functions and receive user input. Second information is displayed in the second portion.

According to some embodiments, an entire device display screen may function in a full configuration mode where the entire available display screen is in a power-on state. For example, a powered-on state may cause the affected part of the display to perform display functions and receive user input, although less, other or different functionality may be associated with the powered-on state. Instructions may be received directing the display to transition from the full configuration mode to a proportional configuration mode. The proportional configuration mode may configure a portion of the display screen in the powered-on state and another portion of the display in a powered-off state (in an example powered-off state, the affected part of the display may be configured to not perform display functions and to not receive user input). Responsive to receiving the instructions, the underlying display technology (e.g., OLED/AMOLED or LCD, etc.) may be directed to continue to power the portion of the display and power-off the other portion of the display.

In another embodiment, a device may be set to a user interface lock state by any predefined manner where the state prevents the device from performing a predefined set of actions. The device may be configured to display an unlock image while in the lock state and detect contact with a touch sensitive display. The device may be configured to determine whether the contact corresponds to an unlock gesture using the unlock image and further configured to determine whether the gesture indicates a proportional configuration mode or a full configuration mode. Responsive to the determination(s) the display may transition to the determined configuration mode.

This specification includes references to “one embodiment” or “an embodiment.” The appearances of the phrases “in one embodiment” or “in an embodiment” do not necessarily refer to the same embodiment. Particular features, structures, or characteristics may be combined in any suitable manner consistent with this disclosure.

“Comprising.” This term is open-ended. As used in the appended claims, this term does not foreclose additional structure or steps. Consider a claim that recites: “An apparatus comprising one or more processor units . . . . ” Such a claim does not foreclose the apparatus from including additional components (e.g., a network interface unit, graphics circuitry, etc.).

“Configured To.” Various units, circuits, or other components may be described or claimed as “configured to” perform a task or tasks. In such contexts, “configured to” is used to connote structure by indicating that the units/circuits/components include structure (e.g., circuitry) that performs those task or tasks during operation. As such, the unit/circuit/component can be said to be configured to perform the task even when the specified unit/circuit/component is not currently operational (e.g., is not on). The units/circuits/components used with the “configured to” language include hardware—for example, circuits, memory storing program instructions executable to implement the operation, etc. Reciting that a unit/circuit/component is “configured to” perform one or more tasks is expressly intended not to invoke 35 U.S.C. §112, sixth paragraph, for that unit/circuit/component. Additionally, “configured to” can include generic structure (e.g., generic circuitry) that is manipulated by software and/or firmware (e.g., an FPGA or a general-purpose processor executing software) to operate in manner that is capable of performing the task(s) at issue. “Configure to” may also include adapting a manufacturing process (e.g., a semiconductor fabrication facility) to fabricate devices (e.g., integrated circuits) that are adapted to implement or perform one or more tasks.

“First,” “Second,” etc. As used herein, these terms are used as labels for nouns that they precede, and do not imply any type of ordering (e.g., spatial, temporal, logical, etc.). For example, a buffer circuit may be described herein as performing write operations for “first” and “second” values. The terms “first” and “second” do not necessarily imply that the first value must be written before the second value.

“Based On.” As used herein, this term is used to describe one or more factors that affect a determination. This term does not foreclose additional factors that may affect a determination. That is, a determination may be solely based on those factors or based, at least in part, on those factors. Consider the phrase “determine A based on B.” While in this case, B is a factor that affects the determination of A, such a phrase does not foreclose the determination of A from also being based on C. In other instances, A may be determined based solely on B.

DETAILED DESCRIPTION

Introduction

Various embodiments of a system and method for managing display power consumption are disclosed. According to some embodiments, an entire device display screen may function in a full configuration mode where the entire available display screen is in a power-on state. For example, a powered-on state may cause the affected part of the display to perform display functions and receive user input, although less, other or different functionality may be associated with the powered-on state. Instructions may be received directing the display to transition from the full configuration mode to a proportional configuration mode. The proportional configuration mode may configure a portion of the display screen in the powered-on state and another portion of the display in a powered-off state (in an example powered-off state, the affected part of the display may be configured to not perform display functions and to not receive user input). Responsive to receiving the instructions, the underlying display technology (e.g., pixels for OLED/AMOLED technologies) may be directed to continue to power the portion of the display and power-off the other portion of the display.

In some embodiments, the portion of the screen (e.g., some or all of the display) that is powered-off may be black or near-black, unresponsive to the touch, or display other characteristics of a display that is not powered. For example, the portion of the display that is powered-off cannot be activated by an errant finger and may be used as a handle for gripping the device. Such configuration may be useful for tasks such as taking pictures with the device comprising the display. The portion of the display that is powered-off may be configurable by or for the user and the rest of the display may continue to provide all or almost all of the full functionality, as described herein.

The screen may be the constant total surface area of the multifunction device on which graphics or text may be electronically provided (or “displayed”), in some embodiments. A display may be configured to display (e.g., illuminate one or more pixels) one or more colors (e.g., other than a black, or other color screen that is the color of the display when powered off) when powered-on, for example. The area of the display that is powered-on may range from 0% (e.g., all black/off) to 100% (e.g., a full display) and anywhere in-between. In some embodiments, the display may be configured to display in grayscale.

0% to 100% of the display or screen may be configured as powered-on, in embodiments. Whatever portion is not configured as powered-on may be configured as powered-off. In embodiments, the portion that is configured as powered-off may be using little to no power from the battery. In embodiments, multiple different portions of the screen may be configured as powered-on while the rest of the screen remains powered-off. For example, the icons representing applications on a smart phone user interface may be powered-on while the space in-between the icons may be powered-off, like islands of powered-on color in a sea of powered-off display area. The display portion may be equal to the total surface area of the sum of the individual powered-on display areas divided by the total screen size.

The portion of powered-on display may be user-configurable, via settings or manipulation of the user-interface, such as described herein, for example. In another example, the portion of powered-on display may be otherwise controlled, by the device operating system or by an application. Embodiments, as described herein, may reduce the amount of screen that is powered-on (e.g., from 20-plus applications to half that or less). In some embodiment, such a configuration may reduce the use of battery power.

In some embodiments, power efficiency may be improved by practicing the methods and configurations described herein, providing for extended battery life for example. A device comprising a display as described herein may provide a user with the ability to control the size of the display such that individual pixels below the powered-off or inactive (e.g., black/dead/unpowered) portion of the display screen are all turned off (e.g., in smart phones using OLED/AMOLED technologies) in embodiments. Some tests have shown that for some devices, something like 67% of the total power drain of a battery may be attributable to the display. In embodiments, the power drain reduction may be proportional to the size of the powered-off portion

In another embodiment, a device may be set to a user interface lock state by any predefined manner where the state prevents the device from performing a predefined set of actions. The device may be configured to display an unlock image while in the lock state and detect contact with a touch sensitive display. The device may be configured to determine whether the contact corresponds to an unlock gesture using the unlock image and further configured to determine whether the gesture indicates a proportional configuration mode or a full configuration mode. Responsive to the determination(s) the display may transition to the determined configuration mode.

In some embodiments first information is displayed in an available display area including a first portion of a display screen in a configuration having a plurality of portions. In some embodiments, the display screen includes the first portion of the display screen, which is configured in a powered-on state to perform display functions and receive user input, and a second portion of the display screen, which is configured in a powered-off state. Responsive to a user indication in the in the first portion, the second portion is added to the available display area by transitioning the second portion to the powered-on state to perform display functions and receive user input. Second information is displayed in the second portion.

The process may be reversible in some embodiments, and a portion of the display screen may be removed from the powered-on state to the powered off state in response to user input. Likewise, the actions described herein as being performed in response to user input may, in some embodiments, be performed in response to system events such as the passage of an amount of time or a signal from an application or system module, or other system events, such as a power-down or sleep signal.

Some embodiments include a redesign of the current user interface of smart phones and hand-held terminals, variously referred to herein as multifunction devices, giving the user the full freedom to touch change their screen and divide it into an active (working) portion and a non-active (non-working, dead) portion depending on their needs and application. Some embodiments achieve numerous valuable benefits such as extending existing battery usage time as a result of the unused electricity saved by the dead portion of the screen, and at the same time using the dead portion of the screen as a grip surface to securely and conveniently use applications such as the camera (similar to the HandlePa™), etc.

Some embodiments present a new simple yet revolutionary user interface (UI) based on a concept and method which will elevate the user's freedom and flexibility and thus change the way smart phone and hand-held terminal users interact with their screen.

In some embodiments, the second information is generated by mathematically upscaling the first information. The second information includes a portion of the first information upscaled for display in both the second portion and the first portion. In some embodiments, third information in the first portion. The third information comprises a portion of the first information upscaled for display in both the second portion and the first portion. In some embodiments, a graphical content data structure including content for display in the available display area is received, and elements of the graphical content data structure are selected for display in the available display area based at least in part on whether the second portion is in a powered-on state.

In some embodiments, a graphical content data structure including content for display in the available display area is received, and elements of the graphical content data structure are scaled for display in the available display area based at least in part on a dimension of the available display area. In some embodiments, a graphical content data structure including content for display in the available display area is received, and elements of the graphical content data structure are scaled for display in the available display area based at least in part on whether the second portion is in a powered-on state.

In some embodiments, a graphical content data structure including content for display in the available display area is received, and a position relative to a background element of a foreground content element of the graphical content data structure is adjusted for display in the available display area based at least in part on whether the second portion is in a powered-on state. In some embodiments, a graphical content data structure including content for display in the available display area is received, and elements of the graphical content data structure are selected for display in the available display area based at least in part on a dimension of the available display area.

Some embodiments may include a means for managing display power consumption. For example, a screen power management module may display first information in an available display area comprising a first portion of a display screen in a configuration having a plurality of portions, responsive to a user indication in the in the first portion, add the second portion to the available display area by transitioning the second portion to the powered-on state to perform display functions and receive user input, and display second information in the second portion, as described herein. The screen power management module may in some embodiments be implemented by a non-transitory, computer-readable storage medium and one or more processors (e.g., CPUs and/or GPUs) of a computing apparatus. The computer-readable storage medium may store program instructions executable by the one or more processors to cause the computing apparatus to display first information in an available display area comprising a first portion of a display screen in a configuration having a plurality of portions, responsive to a user indication in the in the first portion, add the second portion to the available display area by transitioning the second portion to the powered-on state to perform display functions and receive user input, and display second information in the second portion, as described herein. Other embodiments of a screen power management module may be at least partially implemented by hardware circuitry and/or firmware stored, for example, in a non-volatile memory.

Multifunction Device

Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. However, it will be apparent to one of ordinary skill in the art that some embodiments may be practiced without these specific details. In other instances, well-known methods, procedures, components, circuits, and networks have not been described in detail so as not to unnecessarily obscure aspects of the embodiments.

It will also be understood that, although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first contact could be termed a second contact, and, similarly, a second contact could be termed a first contact, without departing from the intended scope. The first contact and the second contact are both contacts, but they are not the same contact.

The terminology used in the description herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used in the description and the appended claims, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

As used herein, the term “if” may be construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” may be construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event],” depending on the context.

Embodiments of electronic devices, user interfaces for such devices, and associated processes for using such devices are described. In some embodiments, the device is a portable communications device, such as a mobile telephone, that also contains other functions, such as PDA and/or music player functions. Other portable electronic devices, such as laptops or tablet computers with touch-sensitive surfaces (e.g., touch screen displays and/or touch pads), may also be used. It should also be understood that, in some embodiments, the device is not a portable communications device, but is a desktop computer with a touch-sensitive surface (e.g., a touch screen display and/or a touch pad). In some embodiments, the device is a gaming computer with orientation sensors (e.g., orientation sensors in a gaming controller).

In the discussion that follows, an electronic device that includes a display and a touch-sensitive surface is described. It should be understood, however, that the electronic device may include one or more other physical user-interface devices, such as a physical keyboard, a mouse and/or a joystick.

The device typically supports a variety of applications, such as one or more of the following: a drawing application, a presentation application, a word processing application, a website creation application, a disk authoring application, a spreadsheet application, a gaming application, a telephone application, a video conferencing application, an e-mail application, an instant messaging application, a workout support application, a photo management application, a digital camera application, a digital video camera application, a web browsing application, a digital music player application, and/or a digital video player application.

The various applications that may be executed on the device may use at least one common physical user-interface device, such as the touch-sensitive surface. One or more functions of the touch-sensitive surface as well as corresponding information displayed on the device may be adjusted and/or varied from one application to the next and/or within a respective application. In this way, a common physical architecture (such as the touch-sensitive surface) of the device may support the variety of applications with user interfaces that are intuitive and transparent to the user.

Attention is now directed toward embodiments of portable devices. FIG. 1 is a block diagram illustrating portable multifunction device 100 with touch-sensitive displays 112 in accordance with some embodiments. Touch-sensitive display 112 is sometimes called a “touch screen” for convenience, and may also be known as or called a touch-sensitive display system.

Device 100 may include one or more optical sensors 164. These components may communicate over one or more communication buses or signal lines 103.

It should be appreciated that device 100 is only one example of a portable multifunction device, and that device 100 may have more or fewer components than shown, may combine two or more components, or may have a different configuration or arrangement of the components. The various components shown in FIG. 1 may be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing and/or application specific integrated circuits.

Memory 102 may include high-speed random access memory and may also include non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Access to memory 102 by other components of device 100, such as CPU 120 and the peripherals interface 118, may be controlled by memory controller 122.

Peripherals interface 118 can be used to couple input and output peripherals of the device to CPU 120 and memory 102. The one or more processors 120 run or execute various software programs and/or sets of instructions stored in memory 102 to perform various functions for device 100 and to process data.

In some embodiments, peripherals interface 118, CPU 120, and memory controller 122 may be implemented on a single chip, such as chip 104. In some other embodiments, they may be implemented on separate chips.

RF (radio frequency) circuitry 108 receives and sends RF signals, also called electromagnetic signals. RF circuitry 108 converts electrical signals to/from electromagnetic signals and communicates with communications networks and other communications devices via the electromagnetic signals. RF circuitry 108 may include well-known circuitry for performing these functions, including but not limited to an antenna system, an RF transceiver, one or more amplifiers, a tuner, one or more oscillators, a digital signal processor, a CODEC chipset, a subscriber identity module (SIM) card, memory, and so forth. RF circuitry 108 may communicate with networks, such as the Internet, also referred to as the World Wide Web (WWW), an intranet and/or a wireless network, such as a cellular telephone network, a wireless local area network (LAN) and/or a metropolitan area network (MAN), and other devices by wireless communication.

In some alternate embodiments, input controller(s) 160 may be coupled to any (or none) of the following: a keyboard, infrared port, USB port, and a pointer device such as a mouse. The one or more buttons (e.g., 208, FIG. 2) may include an up/down button for volume control of speaker 111 and/or microphone 113. The one or more buttons may include a push button (e.g., 206, FIG. 2).

Touch-sensitive display 112 provides an input interface and an output interface between the device and a user. Display controller 156 receives and/or sends electrical signals from/to touch screen 112. Touch screen 112 displays visual output to the user. The visual output may include graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output may correspond to user-interface objects.

Touch screen 112 has a touch-sensitive surface, sensor or set of sensors that accepts input from the user based on haptic and/or tactile contact. Touch screen 112 and display controller 156 (along with any associated modules and/or sets of instructions in memory 102) detect contact (and any movement or breaking of the contact) on touch screen 112 and converts the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages or images) that are displayed on touch screen 112. In an exemplary embodiment, a point of contact between touch screen 112 and the user corresponds to a finger of the user.

Touch screen 112 may use LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies may be used in other embodiments. Touch screen 112 and display controller 156 may detect contact and any movement or breaking thereof using any of a variety of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch screen 112. In an exemplary embodiment, projected mutual capacitance sensing technology is used, such as that found in the iPhone®, iPod Touch®, and iPad® from Apple Inc. of Cupertino, Calif.

The user may make contact with touch screen 112 using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user.

In some embodiments, in addition to the touch screen, device 100 may include a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad may be a touch-sensitive surface that is separate from touch screen 112 or an extension of the touch-sensitive surface formed by the touch screen.

Device 100 also includes power system 162 for powering the various components. Power system 162 may include a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices.

Device 100 may also include one or more optical sensors 164. FIG. 1 shows an optical sensor coupled to optical sensor controller 159 in I/O subsystem 106. Optical sensor 164 may include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor 164 receives light from the environment, projected through one or more lens, and converts the light to data representing an image. In conjunction with imaging module 143 (also called a camera module) optical sensor 164 may capture still images or video. In some embodiments, an optical sensor is located on the back of device 100, opposite touch screen display 112 on the front of the device, so that the touch screen display may be used as a viewfinder for still and/or video image acquisition. In some embodiments, another optical sensor is located on the front of the device so that the user's image may be obtained for videoconferencing while the user views the other video conference participants on the touch screen display.

Device 100 may also include one or more proximity sensors 166. FIG. 1 shows proximity sensor 166 coupled to peripherals interface 118. Alternately, proximity sensor 166 may be coupled to input controller 160 in I/O subsystem 106. In some embodiments, the proximity sensor turns off and disables touch screen 112 when the multifunction device is placed near the user's ear (e.g., when the user is making a phone call).

Device 100 includes one or more orientation sensors 168. In some embodiments, the one or more orientation sensors include one or more accelerometers (e.g., one or more linear accelerometers and/or one or more rotational accelerometers). In some embodiments, the one or more orientation sensors include one or more gyroscopes. In some embodiments, the one or more orientation sensors include one or more magnetometers. In some embodiments, the one or more orientation sensors include one or more of global positioning system (GPS), Global Navigation Satellite System (GLONASS), and/or other global navigation system receivers. The GPS, GLONASS, and/or other global navigation system receivers may be used for obtaining information concerning the location and orientation (e.g., portrait or landscape) of device 100. In some embodiments, the one or more orientation sensors include any combination of orientation/rotation sensors. FIG. 1 shows the one or more orientation sensors 168 coupled to peripherals interface 118. Alternately, the one or more orientation sensors 168 may be coupled to an input controller 160 in I/O subsystem 106. In some embodiments, information is displayed on the touch screen display in a portrait view or a landscape view based on an analysis of data received from the one or more orientation sensors.

In some embodiments, the software components stored in memory 102 include operating system 126, communication module (or set of instructions) 128, contact/motion module (or set of instructions) 130, graphics module (or set of instructions) 132, text input module (or set of instructions) 134, Global Positioning System (GPS) module (or set of instructions) 135, screen power management module 158 and applications (or sets of instructions) 136. Device/global internal state 157 includes one or more of: active application state, indicating which applications, if any, are currently active; display state, indicating what applications, views or other information occupy various regions of touch screen display 112; sensor state, including information obtained from the device's various sensors and input control devices 116; state information that indicates which processes control output of shared audio or visual resource of a vehicle; ownership transition conditions of the shared audio or visual resource; and location information concerning the device's location and/or attitude.

Operating system 126 (e.g., Darwin, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks or RTXC) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components.

Communication module 128 facilitates communication with other devices over one or more external ports 124 and also includes various software components for handling data received by RF circuitry 108 and/or external port 124. External port 124 (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.).

Contact/motion module 130 may detect contact with touch screen 112 (in conjunction with display controller 156) and other touch sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module 130 includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred (e.g., detecting a finger-down event), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Contact/motion module 130 receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, may include determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations may be applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, contact/motion module 130 and display controller 156 detect contact on a touchpad.

Contact/motion module 130 may detect a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns. Thus, a gesture may be detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up (lift off) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (lift off) event.

Graphics module 132 includes various known software components for rendering and displaying graphics on touch screen 112 or other display, including components for changing the intensity of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user, including without limitation text, web pages, icons (such as user-interface objects including soft keys), digital images, videos, animations and the like.

In some embodiments, graphics module 132 stores data representing graphics to be used. Each graphic may be assigned a corresponding code. Graphics module 132 receives, from applications etc., one or more codes specifying graphics to be displayed along with, if necessary, coordinate data and other graphic property data, and then generates screen image data to output to display controller 156.

Text input module 134, which may be a component of graphics module 132, provides soft keyboards for entering text in various applications (e.g., contacts 137, e-mail 140, IM 141, browser 147, and any other application that needs text input).

GPS module 135 determines the location of the device and provides this information for use in various applications (e.g., to telephone 138 for use in location-based dialing, to camera 143 as picture/video metadata, and to applications that provide location-based services such as weather widgets, local yellow page widgets, and map/navigation widgets).

Other modes, exhibiting other types of limited functionality, alone or in combination are also contemplated.

At block 3310, a screen or device may be set to a user interface lock state by any predefined manner where the lock state prevents the device from performing a predefined set of actions. For example, either user stimulus 2560 or system events 2550 may cause the device to be set to a user interface lock state and state information indicating the lock state may be stored as existing state information 2570, in some embodiments. At block 3320, an unlock image may be displayed via the screen while the screen/device is in the lock state. In some embodiments, the element management module may determine from state information 2570 that the device or screen is in the lock state and provide an image of an unlock element or object to be displayed to the screen, by graphics module 132, for example. For example, FIG. 35 illustrates a graphic BAR as an unlock image 3550.

At 3330, contact with the device screen (e.g., a touch sensitive display) may be detected. For example, a touch sensitive display of the device may determine that a user has touched the screen. At 3340, a determination may be made whether the contact corresponds to an unlock gesture using the unlock image. For example, a particular type of contact may be required to unlock the device from the user interface lock state, such that other types of contact do not unlock the lock state. When the contact does not correspond to an unlock gesture using the lock image, the method may continue to block 3350, wherein the device is maintained in the user-interface lock state.

When the contact does correspond to an unlock gesture using the unlock image, the method may continue to block 3360 where a determination is made whether the unlock gesture indicates a proportional configuration mode. For example, in some embodiments, more than one type of contact may be recognized. Different types of contact may be associated with different instructions of how to transition from the user interface lock state. In one embodiment, a certain type of swipe using the unlock image may indicate an instruction to transition to a full configuration mode 3370 and a different type of swipe may indicate an instruction to a proportional configuration mode as indicated at block 3380. FIG. 35, for example, illustrates that when a swipe to the left corresponds with unlock image 3550, a transition to a configuration mode is instructed (3525) and that when a swipe to the right corresponds with unlock image 3550, a transition to another configuration mode is instructed. In some embodiments, the configuration modes to transition to may be full or proportional display configuration modes. The device may transition to the indicated mode (e.g., proportional configuration mode or full configuration mode) after receiving the instruction to transition, in embodiments.

FIG. 34 illustrates a portable multifunction with a display screen in accordance with some embodiments. The illustrated multifunction device 3400 is illustrated comprising display screen 3405. In the illustrated embodiment, the display 3405 is entirely in a powered-off mode. In this particular embodiment, the display 3405 is illustrated in black to indicate that no power is being used to illuminate any portion of the display 3405. Other displays may be other colors when in a powered-off state.

FIG. 35 illustrates a portion of a portable multifunction with a display screen in accordance with some embodiments. In some embodiments, the illustrated multifunction device 3500 of FIG. 35 may be the same multifunction device as illustrated in FIG. 34, but in a different mode. In other embodiments, the illustrated multifunction device 3500 of FIG. 35 may be a different multifunction device than illustrated in FIG. 34.

In the illustrated embodiment, the multifunction device 3500 of FIG. 35 is in a powered-off state. In embodiments, a multifunction device may continuously (e.g., while in the powered-off state) display any of one or more graphical indications while in a powered-off state. In the illustrated powered-off state, the multifunction device 3500 continuously (e.g., while in the powered-off state) displays the time (e.g., 10:10 A.M.), date (e.g., Thursday, Jan. 16, 2014) and indications of notices of emails (e.g., Email icon 3510), SMS, texts (e.g., text message icon 3520), messages (e.g., voice message icon 3515), and the like. Also illustrated in the continuous display are icons for battery power supply amount, local wireless connectivity, WiFi connectivity and carrier signal strength. Other graphical indications of other features are contemplated as well. For example, the unlock image 3550 of the BAR may be continuously displayed in the powered-off state. In some embodiments, some or all such graphical indications cover a limited surface area of the total screen. In some embodiments, such graphical indications consume a limited amount of battery power. In some embodiments, the limited amount of battery power consumed may be in a ratio with the amount of surface area covered. In some embodiments, providing some such information via the continuous display may reduce the wear and tear and chance of mechanical breakdown of use of mechanical (e.g., on-off) switches used to access such information. In other embodiments, the continuous display of some such information may reduce the number of times the device is put into a powered-on state that uses more battery power than the continuous display powered-off mode described herein.

FIGS. 36-38 illustrate multifunction devices in various configurations and states. The displays of the devices are illustrated with various arrangements of the icons, but without the control bar 450 illustrated in FIG. 4, for example. In embodiments (not illustrated) the illustrated devices and displays of FIGS. 36-38 may include control bar 450, without departing from the scope of this disclosure.

FIG. 36 illustrates a portable multifunction device 3600 with a display screen 3605 in accordance with some embodiments. The illustrated embodiment includes the entire available display area 3610. In the illustrated embodiment, 100% of the display 3605 is active (e.g., in a powered-on state configured to perform display functions and/or receive user input). In embodiments, active may indicate display functionality or user-input functionality although additional or different functionality may be associated with an active display area as well. In some embodiments, an active display may indicate that the display is limited to a particular functionality such as display functionality only or receive input functionality only.

FIG. 37 illustrates a portable multifunction 3700 with a display screen 3705 in accordance with some embodiments. In some, but not all embodiments, FIG. 37 illustrates the same multifunction device as in FIG. 36, but in a different configuration mode. In at least one embodiment, device 3700 illustrates the same device 3600, but in a proportional configuration mode. As illustrated, a first portion 3720 of display 3705 is all black, indicating that the first portion is in a powered-off state while the second portion(s) 3730 (e.g., the icon graphical elements) are illustrated in a powered-on state. FIG. 37 illustrates that the portions of the display that are in a powered-on state do not need to be contiguous. In embodiments (not illustrated) the portions of the display that are in a powered-off state need not be contiguous.

FIG. 38 illustrates a portable multifunction device 3800 with a display screen 3805 in accordance with some embodiments. Multifunction device 3800 is illustrated in a configuration with all of the icons grouped together in a single area (a first portion 3815) of the display 3805. The second portion 3820 is illustrated in black to indicate that portion is in a powered-off state. In embodiments, the icons in the first portion may be downsized (e.g., with respect to the icons illustrated in FIG. 36) to fit in a smaller area. In another embodiment, the space between icons may be removed to fit the icons into a smaller portion of the screen. The unused portion of the screen may be directed, instructed or configured into a powered-off state in some configurations.

FIG. 39 is a flow diagram illustrating an embodiment of a method for transitioning a display from a full configuration mode to a proportional configuration mode. The methods described in FIG. 39 may be performed by modules of the screen power management module 3500, singly or in combination.

An entire (e.g., the entire available display screen) display screen may function in a full configuration mode where all of the display screen is in a power-on state, as at block 3900. For example, the screen power management module 2500 may direct the configuration of the screen according to data in existing state information module 2570 that may store the particular configuration mode and the state of the display.

Instructions may be received to transition from the full configuration mode to a proportional configuration mode that configures a portion of the display screen in a powered-on state and another portion of the display screen in a powered-off state as at block 3910. For example, screen transition portion transition conditions module 2580 may listen for particular system events 2550 or indications of user stimulus 2560 that match the transition conditions for the particular configuration mode. In some embodiments, system events may include the battery power level reaching a predetermined level or amount (e.g., 35%) or the user interface receiving an indication of user stimulus indicating a particular mode and sending the instructions for the particular mode to the screen power management module 2500.

Responsive to receiving the instruction(s) to transition from the full configuration mode to a proportional configuration mode, a portion of the display or screen remains powered-on while the other portion of the display is directed to power-off. For example, the utilization determination module 2520 may be configured to work in concert with the configuration module 2510 to transition the display from full configuration mode to proportional configuration mode. In some embodiments, the modules of the screen power management module 2500 send instructions to the graphics module 132, instructing the graphics module to power a portion of the display and to not power the other portion of the display. In embodiments, the process is reversible to put the device back into the full configuration mode where the entire screen is in the powered-on state.

FIGS. 40-42 illustrate a battery level feature that may be used to control the transition into and out of the proportional configuration mode, in embodiments. FIG. 40 illustrates a portable multifunction with a display screen in accordance with some embodiments. Although the black and white drawings of this application limit the illustration, it is intended that the icon elements of FIG. 40 are displayed in various colors and that the background behind the icons of the various applications could be of any color as well. This is in contrast to the device illustrated in FIG. 41, where it is intended that the display of the device be configured such that the black portion illustrated is in a powered-off state and the portions of the icons that appear white in the FIG. 41 could be of any color, such as the illustrated white, grayscale or any other color while in the powered-on state as illustrated.

FIG. 40 illustrates a portable multifunction device 4000 with a display 4005 and a control bar 4050, in accordance with some embodiments. In some embodiments, the display 4005 is in color, while in other embodiments, the display may be in grayscale or black and white.

In the illustrated embodiment, the control bar 4050 is included on the display in the full configuration mode. In some embodiments, the control bar 4050 may not be displayed when the display is in the full configuration mode. In other embodiments, the control bar 4050 may be displayed while the display is in the full configuration mode, as a graphic that may be interacted with via the user interface to instruct the device to transition to the proportional configuration mode, for example.

A battery level auto shift value 4025 is illustrated in FIG. 40. In embodiments, the battery level may be a condition upon which the configuration may be changed from the proportional mode to the full mode or from the full mode to the configuration mode. For example, the device may be configured such that the display transitions from the full configuration mode to the proportional configuration mode when the battery level auto shift value reaches or reaches a point below a certain value (e.g., 35%).

FIG. 41 illustrates a portable multifunction device 4100 with a display screen 4105 and a battery level auto shift value 4125, in accordance with some embodiments. FIG. 41 illustrates that when the battery level auto shift value 4125 achieves a level less than a predefined level (e.g., 35%) the display may be put into a proportional configuration mode, such as those described herein. The proportional configuration mode that is illustrated (34% is less than the example 35% predefined level, so the device has been configured into a proportional configuration mode) configures the display with the black portions of the display in a powered-off state and the white portions of the display in a powered-on state. White is used to illustrate the portions of the screen that are in a powered-on state in the illustrated embodiment due to the nature of black and white drawings. However, the portions illustrated in white as being in a powered-on state may be displayed in any color or grayscale, in embodiments, while the portion illustrated in black remains in a powered-off state. The color of the portion(s) of the display in the powered-off state may be other colors in other embodiments, due to the particular underlying display technology, for example.

FIG. 42 illustrates a portable multifunction device 4200 with a display screen 4205 and battery level auto shift value, in accordance with some embodiments.

FIG. 44 illustrates a portable multifunction device 4400 with a display screen 4405 and available display area 4410, in accordance with some embodiments. FIG. 44 illustrates that the same icon group illustrated in FIG. 43 may be moved to the bottom of the display 4405, such that the first portion 4415 of the display 4405 is in a powered-off state and the second portion of the display 4405 is in a powered-on state.

FIG. 45 illustrates a portable multifunction device 4505 with a display screen 4505 and available display area 4510, in accordance with some embodiments. FIG. 44 illustrates that the same icon group illustrated in FIG. 43 may be moved to the top of the display 4505, such that the first portion 4415 of the display 4405 within the available display area 4510 is in a powered-on state and the second portion 4502 of the display 4405 is in a powered-off state.

The portion of the display that is in the powered-on state may be moved within the display via various methods, such as by dragging via interaction with the user interface (e.g., touch-sensitive surface) or by user configurable settings for example.

FIG. 46 illustrates a portable multifunction device 4600 with a display screen 4605 and an available display area 4610, in accordance with some embodiments. FIG. 46 illustrates that the icon group illustrated in FIG. 45 may include more icons or other graphic elements than those illustrated in FIG. 45. In some embodiments, the graphic object on the display screen may include hidden elements in addition to the elements that are currently visible via the display. For example, the first full icon visible on the left of the first portion 4615 of the display 4605 is an icon for a radio. In the first portion 4515 of FIG. 45, the radio icon was the last icon on the left. In FIG. 46, the user has interacted with the graphical elements of the screen to make the icons scroll such that hidden icons become visible/available and available/visible icons are hidden. This and other types of graphical elements may provide functionality that reduces the amount of area of the display that is powered-on without losing functionality or access to applications.
